RPM front A-arms for the SC8 & RC8B are built with the same principles and design characteristics built into all RPM A-arms. Those design considerations include cleared areas known to rub on the stock A-arms. We also molded in the shock mounts, which means no more lost screws or extra weight from those screws on the arms. To help reduce slop in the suspension, we discarded the stock shock mount pin and setscrew in favor of a new 5-40 screw, which eliminates .004” of slop in the pivot and improves suspension accuracy. Leading and trailing 30-degree edges on the a-arms help the vehicle transition up and over objects too tall for the suspension to clear and as a side benefit, those angles improve suspension aerodynamics. All this comes at a weight identical to the stock arms!

RPM A-arms are molded in our trademark blend of bulletproof nylons and are factory-backed by our industry-leading breakage warranty. Molded in black and sold in sets, including one lower left A-arm, one lower right A-arm, two upper A-arms and all necessary hardware in each package.

Whether you’re out having fun bashing or in the middle of the A-main at a national event, nothing is more frustrating than breaking an A-arm. That’s where RPM steps in. RPM A-arms for the Associated SC8 & RC8B are designed to prevent that from ever happening again. These A-arms are tough as nails and designed to take some serious punishment. Every aspect of the design on these arms is there to either improve strength or durability. Additionally, we’ve cleared the A-arms in areas known to rub on the stock A-arms, allowing extra droop for more suspension travel over rough terrain or big jumps.

Exclusive features of RPM A-arms include: Molded-in shock mounts which means no more lost screws or extra weight from those screws on the arms (each RPM Rear A-arm is actually 3 grams lighter than stock, saving 6 grams of unsprung weight!). Elimination of the stock lower shock mount pin in favor of a new 5-40 screw, which eliminates .004” of slop in the pivot and improves suspension accuracy. Leading and trailing 30-degree edges help the vehicle to more easily transition up and over objects too tall for the suspension to clear and improve suspension aerodynamics.

RPM A-arms are molded in our trademark blend of bulletproof nylons and are factory-backed by our industry-leading breakage warranty. Molded in black and sold in pairs with one left and one right A-arm in each package.
